Plastic-insulated control cables are widely used in industrial automation, power supply systems, municipal engineering, building automation, and other fields, playing a crucial role in signal transmission and circuit control. Their insulation withstand voltage performance directly determines the safety of electrical systems and the stable operation of equipment. Therefore, the cable's factory withstand voltage test is a core quality control step to ensure product quality and prevent potential hazards such as leakage, short circuits, and breakdowns. All tests strictly adhere to the national standard GB/T 9330-2020 to ensure that every batch of products meets compliance standards.

In the procurement of low-voltage cables, the choice of sheath material often determines the cable's service life and safety level. Currently, the mainstream sheath materials on the market are PVC (polyvinyl chloride) and PE (polyethylene), each with its own advantages. Choosing the wrong material not only wastes budget but may also create safety hazards.

Mineral-insulated cables, with their excellent fire resistance, high-temperature resistance, and corrosion resistance, are widely used in power, construction, and metallurgy industries. However, ensuring the quality of the mineral-insulated cables you purchase has become a major concern for many users. This article will provide a detailed introduction to the quality testing methods for mineral-insulated cables, helping you to make informed choices and select high-quality products.

Medium-voltage power cables are a core component of urban power grids, and their laying method directly affects power supply reliability, maintenance convenience, and project costs. Based on different scenario requirements, common laying methods can be divided into the following five categories; scientific selection can maximize benefits.

In the field of power transmission, safety and reliability are always core requirements. Flexible mineral-insulated fire-resistant cables, with their superior fire resistance and flexible installation characteristics, have become "safety guardians" in many critical scenarios.

In the fields of power transmission and signal control, PVC insulated multi-core cables have become the preferred choice for numerous scenarios due to their superior performance and wide applicability.
